Another useful package for plotting maps is “ggmap”. As you may guess, “ggmap” follows the graphing approach of “ggplot2”.

Let’s look for specific types of food
dat$optionaltext[1:3]## [1] "Tacos, Burritos, Tortas, Quesadillas, Mexican Drinks, Aguas Frescas"
## [2] "Cold Truck: sandwiches, drinks, snacks, candy, hot coffee"
## [3] "Cold Truck: Pre-packaged Sandwiches, Various Beverages, Salads, Snacks"foods <- dat$optionaltext[1:10]Use str_detect() (or equivalently grep()) to match “Burritos” and “burritos”.
